Canadians should expect more extreme weather like the current heat wave baking southern Ontario and Quebec in the future because of climate change, a leading climatology professor says.

“My strong opinion is that these kinds of extremes are something you would expect in a warming world, and expect to happen more frequently,” Harry McCaughey, a professor of climatology at Queen’s University, told CTV.ca.

McCaughey says climate models show that overloading the climate with carbon and water vapor (a byproduct of a warming globe) makes the system much more unstable.

Ok, typical short-news-cycle-driven story about something observed (it’s hot!!) that’s happening now but exists in geological time (tens of thousands of years).

Even more telling is the “climate change fatigue” expressed in the comments section of the post which seems to be in a condemning consensus about this news story:

“That global warming sure is horrible, look at all those pictures of people having fun at the beach ! We should really try and stop this thing immediately, call your local politicians, I know I am ! On second thought ……….. last winter was horrible, bring on global warming !” — NM

“There was a three to four day spread in December in Edmonton last winter where it was record setting cold, -49 w/ windchill of ~ -55 to -60. Where was Mr. McCaughey then ? In fact last winter was the coldest in some areas in over 30 years, remember ice in Florida where they lost over $100 million in orange crops. I really don’t care if global warming is happening or not, but seriously the more the marrier if that means I have to go through another winter like last year !” — Sure …….

“As a child I remember summers always being hot in July. Southern Saskatchewan was always 90 to 105 degrees. IMO we are just too used to our comforts-central heating in winter and airconditioning in summer.” — jjaycee

“I was wondering how long it would take until the media blamed this latest of many heatwaves dating back hundreds of years on climate change.*sigh*” — Mike

“Yes, it is called summer, Dr. Doom. Normally, summer is preceded by gradual warming following winter, which can be extremely cold.” — Lou
